I-PHD-22HF-2727
Uhlolojikelele
I-H serie backplane ikhweza izithiyo zokuphepha ezihlukanisiwe ohlangothini lokutholwa: PHD-22HF-2727, okokufaka kwedijithali nokuphumayo, okokufaka okukabili kanye nokuphuma kabili.
Umgoqo ohlukanisiwe ungaguqula iswishi ye-proximity kanye nokokufaka kokuxhumana endaweni eyingozi kusignali yokuxhumana edluliselwe futhi uyidlulisele endaweni ephephile.
I-relay ephumayo ifakwe inkinobho yokukhetha yesimo esithi "VULIWE/CIMILE". Ngaphezu kwalokho, kukhona isignali yokufaka i-short-circuit noma inkomba ye-alamu evulekile, isifunda sinikeza amandla enzwa yokufaka.
Lo mkhiqizo udinga ukunikezwa kwamandla okuzimele.
Inkomba yesimo sesignali isethwe ekukhanyeni okubomvu nokuphuzi ukuze ibonise isimo sokusebenza kwe-relay ephumayo, uma ingeyethusayo bese ukukhanya kubabomvu, ngesikhathi sokusebenza okuvamile ukukhanya kubaphuzi.
Imininingwane
| I-voltage yokuhlinzeka | 20~35VDC, ukusetshenziswa kwamandla |
| Isignali yokokufaka | Shintsha noma i-NAMUR proximity detector |
| Ukunikezwa kwamandla kagesi wenzwa esizeni | 8V |
| Izici zokufaka isignali | Okufakwayo esizeni: >2.1mA, kusho VULIWE; Okokufaka okusendaweni: |
| Izici zokukhipha kanye ne-alamu edluliselwe | Isikhathi sokuphendula: 20ms, amandla okushayela: 250VAC/2A, 30VDC/2A ngaphansi komthwalo ophikisayo |
| Izici zokukhipha kanye ne-alamu edluliselwe | Lapho inkinobho yokudayela i-K1, i-K3 isehlangothini elithi "ON", ukuphuma kwe-relay "KUVALIWE" Uma inkinobho yokudayela i-K1, i-K3 isehlangothini elithi "VALIWE", okokukhiphayo ku-"VULIWE" Lapho inkinobho yokudayela i-K2, i-K4 isehlangothini elithi "ON", isifunda sikhetha okubonisa ukusebenza kwe-alamu yokudlulisa ukukhanya okubomvu. |
| Umsebenzi we-alamu wokukhanya wokukhanya | Okokufaka okusendaweni>7mA, i-alamu ye-short-circuit (SC) , okokufaka okusendaweni Okokufaka kothintana naye okushintshayo, lapho umsebenzi wokuthola ukunqanyulwa udingeka, isixhasi esingu-22KΩ kufanele sixhunywe ngokuhambisana kuzo zombili iziphetho zeswishi (Sicela ubone othintana naye weswishi II kumdwebo wezintambo ongezansi) |
| Inombolo yokokufaka nokuphumayo | 2 okokufaka 2 okukhiphayo |
| Imishini yasensimini esebenzayo | Oxhumene naye okomile noma ukushintsha kwe-NAMUR okusondele ngokuhambisana nezinga le-DIN 19234 |
| Ipharamitha yezinga lokushisa | Izinga lokushisa lokusebenza: -20 ℃~+60 ℃, izinga lokushisa lokulondoloza: -40 ℃~+80 ℃ |
| Umswakama ohlobene | 10% ~ 95% RH akukho ukufingqa |
| Amandla e-Dielectric | Phakathi kohlangothi oluphephile lwangaphakathi kanye nohlangothi olungaphephile ngaphakathi (≥3000VAC/min); phakathi kokunikezwa kwamandla kanye netheminali engaphephile ngokwe-intrinsically (≥1500VAC/min) |
| Ukumelana ne-insulation | ≥100MΩ (phakathi kokufaka/okuphumayo/ukunikezwa kwamandla) |
